The Lee & Walker is almost certainly a reprint - complete with plate number - of the Firth, Pond & Co. print, which according to the plate number would be 1861 or 1862. (HMB also lists a Schott ed. of La Marseillaise in this series as early as 1848, p.104 HMB. Original 1848 Schott plate of La Marseillaise was 9929.)
